An UHDTV broadcasting system employing MPEG Media Transport (MMT) as its media transport protocol has been proposed for hybrid delivery of content. On the basis of this proposal, an MMT-based UHDTV broadcasting system has already been standardized and is being developed in Japan. This paper describes the structure of that system. The system supports hybrid delivery and has mechanisms to carry Universal...
This paper represents the general design solution for three-dimensional graphical user interface (GUI) solution for the application for television receivers. Concerning the user experience as well as the fact that users are used to 2D GUI, most of the elements in this solutions are in 2D and combined together within 3D world.
GINGA-Nested Context Language (GINGANCL) is a subsystem of GINGA, the standard for the Brazilian mobile broadcasting service, and it specifies the mechanisms and services used to enable various interactive data services. The integral part of GINGA-NCL is the NCL declarative language that provides non-invasive control of a multimedia presentation in time and space, as well as user interaction. In particular,...
Explain the information management process with mathematic analysis to the channel between sender's (information resources) space and receivers' (audience's) space. Prove homotopia relation is equivalent relation. Instead and combine the channels in homotopia audience's space considering some elements such as cost, speed, convenience, etc. The managers should select better index tools and transmitting...
We propose a new efficient file-transport mechanism, which is required for constructing a hybrid content delivery system incorporating broadcasting and telecommunication. Such a system combines different types of delivery channels to make effective content delivery possible. In the system, files of coded audio/video and metadata are transferred as IP packets over broadcasting channels as well as telecommunication...
We consider data-streaming from an access point to multiple receivers, which is modeled as packet erasure channel. A simple network coding is shown to achieve larger rate region than without network coding, using minimal control information. The performance is characterized exactly using state transition graph. The scheme is then mapped to an information theoretic formulation for broadcast channel...
The paper presents an approach to the design of layered BICM MIMO systems using multi-stage iterative decoding and Soft Output M-Algorithm (SOMA) based component decoders. The systems consider transmission based on multilevel coding linked to hierarchical QAM constellations. The receivers are iterative designs with a view to supporting high-rates. These receiver designs can also be used to obtain...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
